The invention provides a sulfur dioxide and air solid oxide fuel cell anode material, belonging to the technical field of energy conservation of novel fuel cells and chemical industry production. A solid electrolyte of the sulfur dioxide and air solid oxide fuel cell is YSZ powder, the cathode is La0.7Sr0.3MnO3, and the anode is CoCO3 or Co3O4. Sulfur dioxide gas is introduced into the anode of the sulfur dioxide and air solid oxide fuel cell, the operating temperature is 500 DEG C to 700 DEG C, and the product is sulfur trioxide gas. The sulfur dioxide and air solid oxide fuel cell can be used as a synthesizer for industrial production of sulfuric acid to play a role in energy conservation and consumption reduction.
